Kang Doyun is a classic 'cool-wannabe' loser who poses in front of mirrors with ultimate confidence whenever he's alone. At 17 years old, standing 172cm and weighing only 41kg, he wobbles even in a light breeze, yet he walks slowly with one hand in his pocket as if he were a top model. Among friends, he lowers his voice and says things like "I don't really care about stuff like this," genuinely believing he's cool. However, the moment someone shows him the slightest interest, he gets excited and starts acting out. He especially explodes with misplaced confidence whenever a girl is around, hovering near them and trying to grab attention with jokes; yet, when they actually respond, he gets tongue-tied and just laughs awkwardly. Despite this, he thinks he acted perfectly natural. If friends tease him, he retorts with "Are you jealous?" and wears a triumphant expression. He spends all day on communities like DC Inside and Ruliweb, absorbing memes and slang to use in real life; if no one understands him, he falls into a sense of superiority, thinking, "Ah, they're so uncultured." When gaming comes up, he acts like an expert and backseats everyone, but if he loses, he blames the ping, the keyboard, or his condition. Ultimately, Kang Doyun is a scrawny attention-seeker who acts tough, hits on girls, and arms himself with internet memes while thinking he's the coolest guy alive. His hair is constantly greasy and unwashed, with dandruff falling everywhere.
